`
`REMARKS
`
`Claims 1—24 are pending. Claims 1—7, 17-20 and claims 22-24 are withdrawn from
`
`consideration. By this Amendment, no claims are canceled, claims 1, 8, 9 and 17 are amended
`
`and new claims 25—27 are added
`
`Election/Restriction
`
`Initially, Applicants note that the disposition of claims in the Office Action Summary is
`
`incomplete. The disposition of claims indicates that claims 8-16 and 21 are pending in the
`
`application but makes no comment on the status of claims 1-7, 17-20 and 22-24 which also
`
`remain pending. As indicated above, claims 1-24 remain pending in the application, while
`
`Applicants have requested that claims 1-7, 17-20 and 22-24 be withdrawn from consideration.
`
`Applicants respectfially request that the Examiner correct the record to reflect the disposition of
`
`the claims in the case as it currently stands. In particular, Applicant respectfully requests that the
`
`Examiner indicate that claims 1-7, 17-20 and 22-24 are withdrawn from consideration and have
`
`not been canceled from the application.
`
`Claim Rejections — 35 U.S.C. § 103
`
`The Office Action rejected claims 9 and 12—15 under 35 U.S.C. § 103(a) as being
`
`unpatentable over Niazi (US. 6,638,268) in View of Solar (US. Publication 2003/0195546).
`
`Initially, while the Office Action states that claims 9 and 12-15 are so rejected, the Office Action
`
`then continues on to address the limitations of claim 8. Applicant therefore assumes that a
`
`typographical error was made and the Examiner intended to refer to claims 8 and 12-15.
`
`Applicants respectfially traverse the rejection.

`

`Claim 8 and new claim 25
`
`Application No. l l/4l6,629
`
`Amended claim 8 recites the limitations “the intermediate portion including a partially
`
`cylindrical portion defining an opening along and accessible from a longitudinal side thereof, the
`
`longitudinal side being generally parallel
`
`to a long axis of the second lumen,
`
`the opening
`
`extending substantially along at least a portion of a length of the intermediate portion.”
`
`The Office Action admits that Niazi does not disclose an elongate structure with a
`
`cylindrical portion defining an opening along a side thereof.” However, the Office Action
`
`asserts that Solar discloses such a structure. Applicants respectfially traverse the assertion and
`
`the rejection.
`
`
`
`As can be seen in representative Fig. 8 of Solar, reproduced above, Solar discloses no
`
`“opening along a side” of a portion as recited in claim 8 and described, depicted and claimed in
`
`the application. Note that the side is defined as being generally parallel to the long axis of the
`
`second lumen. Arrows have been added to indicate openings only on the ends of the device
`
`disclosed by Solar. These ends are not generally parallel to a long axis of the second lumen as
`
`recited in claim 8. Amended Claim 8 further recites “the opening extending substantially along
`
`at least a portion of a length of the intermediate portion.” Solar does not disclose or suggest this
`
`13
`
`Page 13
`
`Medtronic Exhibit 1411
`
`Page 13
`
`Medtronic Exhibit 1411
`
`

`

`Application No. 1 1/416,629
`
`limitation either. Rather, Solar discloses that “[t]racking member 7 has an open proximal end 11
`
`and an open distal end 7.” Paragraph 0026. However, Solar does not disclose or suggest “the
`
`intermediate portion including a partially cylindrical portion defining an opening along a
`
`longitudinal side thereof, the longitudinal side being generally parallel to a long axis of the
`
`second lumen, the opening extending substantially along at least a portion of a length of the
`
`intermediate portion” as recited in claim 8.
`
`
`
`An example structure can be seen, for example, in Figs. 13, 15 and 16 of the present
`
`application.
`
`In particular, Figs. 15 and 16 depict an example opening and partially cylindrical
`
`portion identified by the arrows added. Thus, at least this limitation of claim 8 is not disclosed or
`
`suggested by the cited prior art and the Office Action does not make out a prima facie case of
`
`obviousness for at least this reason.
`
`Claim 8 previously recited the limitations:
`
`“an elongate structure defining a second lumen along at least part of a length thereof and
`
`being sized to pass through the first lumen of the guide catheter, the elongate structure
`
`including:
`
`a flexible distal tip portion;
`
`14
`
`Page 14
`
`Medtronic Exhibit 1411
`
`Page 14
`
`Medtronic Exhibit 1411
`
`

`

`a flexible reinforced portion proximal to the flexible distal tip portion.”
`
`These limitations are now partially contained in new claim 25.
`
`Application No. 1 l/416,629
`
`The Office Action indicates that “Niazi also discloses an elongate structure 52 defining a
`
`second lumen along its length and being sized to pass through the first lumen of the guide
`
`catheter 51.” The Office Action goes on to state that “the elongate structure has flexible tip”
`
`citing Col. 5, line 14. Niazi recites:
`
`“Inner guiding catheter 52 made of a soft, pliable material such as silicone, and in this
`
`example is 2.6 mm in outer diameter and 2.3 mm in inner diameter. It has no
`
`longitudinal braiding, which makes it extremely flexible and able to conform to various
`
`shapes. Inner catheter 52 is designed to advance over a guide vw're into a side branch of
`
`the coronary sinus, in conjunction with the obturator 53. Its flexibility allows it to
`
`negotiate tortuous vessels and side branches that originate from the coronary sinus at an
`
`acute angle.” Column 5, Lines 15-22.
`
`Thus, Niazi clearly indicates that the flexible tip referred to at Col. 5, line 14 is the tip of
`
`inner guide catheter 52 which is a separate structure from guide catheter 51 which is not
`
`indicated to have a flexible tip portion.
`
`The Office Action goes on to state that a flexible reinforced portion proximal to the
`
`flexible tip portion is described at C0]. 6, lines 46—54. Applicant respectfully traverses the
`
`assertion, Col. 6, lines 46-54 of Niazi describes an alternate version of the inner catheter 52
`
`which is depicted in Figure 6, and reference to Figure 6 clearly shows that the reinforced portion
`
`is not proximal to the flexible portion that is described at Column 5, Lines 15-22 but that in the
`
`described altemate embodiment the reinforced portion extends all the way to the distal end of the
`
`depicted inner guide catheter 52. The alternate embodiment has no distal portion that is “soft
`
`and pliable” as is the embodiment disclosed at Column 5, Lines 14—27, which is described as
`
`15
`
`Page 15
`
`Medtronic Exhibit 1411
`
`Page 15
`
`Medtronic Exhibit 1411
`
`

`

`having “no longitudinal braiding.” Instead, the alternate embodiment is reinforced all the way to
`
`its distal end.
`
`Application No. 1 1/416,629
`
`
`
`Thus, the flexible tip is part of one version of the inner guide catheter while the depicted
`
`reinforced portion is the tip of another embodiment of the inner guide catheter.
`
`In particular,
`
`Niazi does not disclose or suggest “a flexible distal tip portion” and “a flexible reinforced portion
`
`proximal to the flexible distal tip portion” as recited in independent claim 8. Thus, aside from
`
`potential hindsight reasoning based on the Applicants’ disclosure, the Niazi reference does not
`
`disclose or suggest the limitations recited in the claims of the present application and no reason is
`
`presented as to why one would arrange the flexible distal tip portion and the and the flexible
`
`reinforced portion relative to each other as recited in the presently pending claims. For these
`
`further reasons, the present invention as claimed is not rendered obvious over Niazi in View of
`
`Solar. Applicants respectfully request that the Examiner withdraw the rejection.

`Medtronic Exhibit 1411
`
`

`

`Application No. 1 1/416,629
`
`The Office Action goes on to indicate “the elongate structure 52 when extended through
`
`the lumen guide catheter 50, and beyond the distal end of the guide catheter, it is capable (sic) of
`
`assisting in resisting shear forces exerted by any device passed through the second lumen and
`
`beyond the flexible tip that would dislodge the guide catheter from the branch artery.” The
`
`Office Action cites no evidence in Niazi to support this conclusory assertion and Applicant finds
`
`no indication of this limitation being disclosed or suggested in the Niazi reference. Absent
`
`supporting evidence, Applicant respectfully takes the position that the office action does not
`
`make out a primafacie case of obviousness for at least this additional reason because the Office
`
`Action does not show that this limitation is disclosed or suggested in the cited prior art.
`
`Applicants respectfiilly request that the Examiner withdraw the rejection.
`
`With regard to claim 8 and limitations that are now, in part, presented in dependent claim
`
`25, the Office Action cites to paragraph 25 of Solar as supporting the assertion that the tracking
`
`member 7 of Solar is rigid and becomes more flexible as it moves distally. Paragraph 25 of
`
`Solar states:
`
`“Preferably, advancement member 5 (also depicted in Fig. 8 of Solar above) is rigid
`
`at its proximal end and becomes increasingly more flexible as it extends distally.
`
`This may be accomplished by a number of ways known in the art, including, but not
`
`limited to, tapering, selective heat treatment and/or forming advancement member 5
`
`from a composite of materials with various properties.”
`
`According to Solar, it is only “advancement member 5” that is described as being “rigid
`
`at its proximal end” and “increasingly more flexible as it extends distally.” Thus, Solar does not
`
`disclose or suggest the claimed limitations “a flexible distal tip portion; a flexible reinforced
`

`Medtronic Exhibit 1411
`
`Page 17
`
`Medtronic Exhibit 1411
`
`

`

`Application No. 1 1/416,629
`
`portion proximal to the flexible distal tip portion; and a substantially rigid portion proximal to
`
`the reinforced portion” as recited in claim 8 in combination with new claim 25. Therefore, the
`
`Office Action does not make out a prima facie case of obviousness for at least this additional
`
`reason.
`
`The Office Action further asserts that the device of Solar has “partially cylindrical
`
`portion 7 with an opening in the circular sides that extends substantially discloses the apparatus
`
`as claimed, it does not disclose along a length of a rigid portion.” Applicant respectfully notes,
`
`that as demonstrated above, Solar does not disclose or suggest a partially cylindrical portion as
`
`recited in claim 8 and defined in the specification of the present application nor does it disclose
`
`any openings in the side of a partially cylindrical portion as recited in claim 8. The indicated
`
`portion of Niazi is a full cylinder. An example partially cylindrical portion is depicted for
`
`example in Figs. 15 and 16 of the present application which are reproduced above.
`
`Thus, the cited prior art Office Action does not anticipate or render obvious amended
`
`claim 8 because the prior art cited does not disclose or suggest all of the elements recited in
`
`claim 8. Applicants respectfully request that the Examiner withdraw the rejection.
`
`Claims 9-16, 21 and new claim 25 depend directly or indirectly from claim 8 and should
`
`be patentable for at least the same reasons as claim 8. Applicants respectfully request that the
`
`Examiner withdraw the rejections.
`
`Claim 9
`
`Claim 9 recites the limitations “wherein the substantially rigid portion defines a plurality
`
`of relief cuts therein,
`
`the relief cuts controlling the rigidity of at
`
`least a portion of the
`
`substantially rigid portion.” With regard to claim 9, the Office Action cites to Adams (US

`
`Medtronic Exhibit 1411
`
`

`

`Application No. 1 1/416,629
`
`2004/0127927) which in turn cites to Fucci (US 5,601,586 and 5,411,514) as disclosing relief
`
`cuts. However, the single “spiral relief cut” of Adams and Fucci would not create the invention
`
`as claimed and would destroy the function of the present invention because there would be
`
`nothing in the present invention as claimed in claim 9 to hold a spiral cut tube together and
`
`facilitate the passage of another device through the lumen of the spiral cut tube as compared to
`
`the multiple staggered relief cuts claimed and depicted for example in Figs. 10 and 11.
`
`Applicants respectfully request that the Examiner withdraw the rejection.
`
`Claim 13
`
`With regard to claim 13, the Office Action indicates “Niazi and Solar further disclose
`
`decreasing the rigidity (directly related to flexural modulus) as one moves distally down the
`
`device. Applicant respectfully traverses this assertion. While the statement regarding Niazi and
`
`Solar may be true, Claim 13 recites “further comprising, starting at a distal end, a polymer
`
`exterior” and then goes on to define the polymer exterior as “having a first portion having a first
`
`flexural modulus, a second portion having a second flexural modulus greater than the first
`
`flexural modulus, a third portion having a third flexural modulus greater than the second flexural
`
`modulus and a fourth portion having a fourth flexural modulus greater than the third flexural
`
`modulus.” The Office Action provides no citation to the references as to where this disclosure is
`
`allegedly found and Applicants cannot identify any such disclosure in either the Niazi or the
`
`Solar reference other than the comments related to the advancement member discussed above.
`
`The advancement member is not a polymer exterior as recited in claim 13. As such, neither the
`
`Niazi reference nor the Solar reference discloses or suggests a device with a polymer exterior
`
`meeting the recited limitations related to flexural modulus. Thus, Applicant respectfully takes

`

`

`the position that the Office Action has not made out a prima facie case of obviousness with
`
`regard to claim 13 for this additional reason. Applicants respectfully request that the Examiner
`
`Application No. 1 l/4l6,629
`
`withdraw the rejection.
`
`With regard to claims 14 and 15, the Office Action asserts “it would have been an
`
`obvious matter of design choice to a person of ordinary skill in the art to assign specific flexural
`
`modulus and length to each section of Niazi, because Applicant has not disclose if the lengths
`
`and modulus provide an advantage, is used for a particular purpose or solves a stated problem.”
`
`Applicant respectfully traverses the assertion. The Board of Patent Appeals and Interferences
`
`has an addressed the issue of rejections based on “obvious matter of design choice” in ex parte
`
`Roger Massey. Appeal No. 2003-1660, slip op. at 6. The Board stated with regard to rejections
`
`under § 103 of the patent statute "It is not enough to merely allege that something is 'well
`
`known,‘ is an ‘obvious matter of design choice,‘ or 'lacks criticality."‘ The Board then cited In re
`
`Lee, which indicates "The factual inquiry whether to combine the references must be thorough
`
`and searching.
`
`It must be based on objective evidence of record. This precedent has been
`
`reinforced in myriad decisions and cannot be dispensed with." 277 F.3d 1338, 1343, 61 USPQ
`
`2d 1430, 1433 (Fed. Cir. 2002). The patent office must not only assure that the requisite findings
`
`to support a conclusion of obviousness are made, based on evidence of record, but must also
`
`explain the reasoning by which the findings are deemed to support the agency’s conclusion.
`
`In
`
`re Lee at 1434. Thus the Office Action does not make out a prima facie case of obviousness
`
`with relation to claims 14 and 15 for at least this additional reason. Applicants respectfully
`
`request that the Examiner withdraw the rejection.

`Application No. 1 l/4l6,629
`
`Applicant has also amended withdrawn independent claims 1 and 17 to recite the
`
`limitation of claim 8. Thus, claims 1-8 and 17-24, 26 and 27 should be allowable as well.
`
`Applicants, respectfully request that these claims be rejoined in the application upon a finding of
`
`allowable subject matter in claim 8.
`
`In view of the foregoing, it is submitted that this application is in condition for allowance.
`
`Favorable consideration and prompt allowance of the application are respectfully requested.
`
`The Examiner is invited to telephone the undersigned if the Examiner believes it would
`
`be useful to advance prosecution.
